What to do
Operators must stop using ASRP versions prior to 136.01 for new repairs and damage assessments from June 13, 2023. For Group A BD-500-1A10 aircraft, all existing repairs and damage assessments on affected structures must be identified and reviewed within 24 months of June 13, 2023, following ACLP Service Bulletin BD500-530011 Issue 003 instructions. Repairs using REOs issued before January 1, 2023, are prohibited for new repair dispositions.
Summary
Airworthiness Directive CF-2023-37R1 is a Canadian regulatory update addressing Airbus Canada Limited Partnership (ACLP) model BD-500-1A10 and BD-500-1A11 aircraft. It focuses on verifying aircraft repairs and damage assessments in light of revised structural stress data and operational loads for the A220 aircraft. The directive ensures compliance with updated repair manuals and engineering orders to maintain structural integrity.
What changed
This revision removes previous restrictions on which source data must be used for assessing new damage and repairs while maintaining prohibitions on outdated data. It references the updated ACLP Service Bulletin BD500-530011 Issue 003 and clarifies that repairs using repair engineering orders issued after a specific date are validated and do not require additional approval. It also completes corrective actions for model BD-500-1A11 aircraft as mandated in a separate directive.
Why it matters
This directive is critical for operators, maintenance organizations, and compliance teams to ensure that all structural repairs and damage assessments conform to the latest approved stress data and repair standards. Using outdated repair data could compromise aircraft structural margins, potentially affecting safety and regulatory compliance. Adhering to this directive helps maintain airworthiness and avoid unauthorized repairs.
